Creating new instances of a covergroup using an array

Hello,

it would be really helpfull to understand more if you share exact Error which you are getting.

However,few things are missing in above code

  1. you need to create array/define array size before you new each cg instance. because when you say “skew_cg[i]” it doesnt know skew_cg is array or not!!
  2. Last time when i tried to create array of cover-group and define cover-group inside class i was getting compilation issue as tool was not able to resolve the cover-group definition. thats why wrote cover-group outside class.

so try below code, I am sure it will work.



covergroup skew_val_cg (int skew_val_vl);
coverpoint skew_val_vl {
bins skew_range_1 = {[124:0]};
bins skew_range_2 = {[325:125]};
bins skew_range_3 = {[526:326]};
bins skew_range_oor = {[1100:929]};
}
endgroup : skew_val_cg

class sample_class extends uvm_component;
int skew_val_vl[20];

skew_val_cg cg_inst[20];

function new(string name, uvm_component parent = null);
super.new(name, parent);
foreach(skew_val_vl[i])
cg_inst[i] = new(skew_val_vl[i]);
endfunction // new
endclass : sample_class
